7 Total Harmonic Distortion Protection Functions Over Temperature Protection Short Circuit Protection Open Lamp Protection External Thermal Protection NTC Protection Current Floor Decreases output current, returning to normal after over temperature is removed. Auto Recovery. The power supply will shut off all of the output and restarts 1 minute later when output operates in a short circuit condition. Auto Recovery. The power supply will shut off all of the output and restart 1 minute later when output operates in an open lamp condition. R kohm R kohm When R_NTC falls below R1, External Thermal Protection is triggered, reducing output current until R2 is reached. When R_NTC is less than R2, output current is reduced to the programmed Protection Current Floor. 5%Ioset 60%Ioset 100%Ioset 5%Ioset>Iomin (default setting is 60%) Iomin 60%Ioset 100%Ioset 5%Ioset Iomin (default setting is 60%) Dimming 010V Dimming The recommended implementation of the dimming control is provided below. Implementation 1: DC Input 7 / 11

8 Notes: 1. The dimmer can also be replaced by an active 010V voltage source signal or passive components like zener. 2. Do NOT connect Dim to the output Vout or Vout+, otherwise the driver will not work properly. 3. If 010V dimming is not used, Dim + should be open. PWM Dimming Implementation 2: Positive logic Implementation 3: Negative logic Timing Dimming Time dimming control includes 3 kinds of modes, they are Self AdaptingMidnight, Self Adapting Percentage and Traditional Timer. Self AdaptingMidnight: Automatically adjusts the dimming curve based on the ontime of past two days (if difference <15 minutes), assuming that the center point of the dimming curve is midnight local time. Self AdaptingPercentage: Automatically adjusts the ontime of each step by a constant percentage = (actual ontime for the past 2 days if difference <15 min) / (programmed ontime from the dimming curve). Traditional Timer: Follows the programmed timing curve after power on with no changes. Output Lumen Compensation Output Lumen Compensation (OLC) may be used to maintain constant light output over the life of the LEDs by driving them at a reduced current when new, then gradually increasing the drive current over time to counteract LED lumen degradation. 8 / 11
